I can confirm: The "Serial Port" drop-down is empty. `git bisect` says:

2b01a64ff2562f7a4eed6bea03b5b9d68bc5bdf3 is the first bad commit

Here you go. It looks like the program expects the captions of serial devices
to include the word "COM":

0024:trace:wbemprox:wbem_services_ExecQuery 0851A1D0, L"WQL", L"SELECT Caption,
Service FROM Win32_PnpEntity WHERE Caption LIKE '%(COM%'", 0x30, 00000000,

This query couldn't have returned an entry before this patch but there may be a
fallback path that's no longer taken after this patch.

I tested this query "SELECT Caption, Service FROM Win32_PnpEntity WHERE Caption
LIKE '%(COM%'" on windows and one entry showed up (something like 'Intel device
.... (COM3)' 
The reported classguid was {4d36e978-e325-11ce-bfc1-08002be10318} (ports) but
this doesn't even show up when I run this query in wine.

If you run the program like 'WINEDLLOVERRIDES=wbemprox=d wine
LokProgrammer.exe'  the list of serial ports is back (as  like Hans said
another codepath is chosen)
Not sure what to do now.

It probably expects at least one entry. I'm looking into adding support for
this but it will not be code freeze material.
